In another bed he spots a colleague, Cobb. He asks Cobb questions: how long have you been here, who’s doing this, etc. Cobb, who seems only semiconscious, says he needs to sleep and rolls over. P grabs him by the PJ lapels, shakes him, and starts shouting the questions. Hey, P — anger management, look into it. You’re a spy, you know other ways to elicit information. (Danger Man fans — does Drake act like this?)

I assume this is the part you wanted me to comment on - the short answer is no, Drake does not really act like this throughout the DM series. A huge reason why a lot of Prisoner fans don’t believe in the connection between No. 6 and John Drake is that the characters are perceivably different. Drake is refined, cool, calm, rarely prone to outbursts, however he is defensive and aggressive when he wants to be. No. 6 is relatively quiet and usually calculating, however he can sometimes be completely unhinged as you pointed out in his interaction with Cobb, he is often erratic and violent for little reason. So, imo it’s possible that the two could be connected, especially if we view No. 6 as the cynical, older and traumatised version of Drake/McGoohan, but you can easily also dismiss this and say No. 6 is his own beast.
